🔌 Function

Carries power and signals between the units it connects, made up to the lengths and connector positions of the installation.

⚠️ Common Signs of Failure

• An intermittent fault that changes when the loom is moved or flexed
• Fault codes appearing and clearing, or several unrelated sensor faults at once
• Green corrosion inside a connector, or a terminal backed out of its housing
• A hot smell, or insulation hardened and discoloured near a terminal
• Chafed sleeve or bare copper where the loom crosses a bracket or a hot surface

🛠️ Service Notes

• Check the individual connectors, pins and seals before condemning the whole loom, as most faults sit at a pin or a chafe point
• Isolate the batteries first, route the new harness exactly as the original ran, and secure it at every clip so it cannot chafe or hang on a hot surface
